Magnetization reversal more rapidly by using an ultrashort square-wave laser pulse
Xiaoqiang Zhang, Yong Xu, Weisheng Zhao
With the feature of low-power magnetization manipulation at an ultrashort time scale, all optical switching (AOS) has been propelled to the forefront in investigations. To further…
Extending the Propagation Distance of a Silver Nanowire Plasmonic Waveguide with a Dielectric Multilayer Substrate
Douguo Zhang, Yifeng Xiang, Junxue Chen +9
Chemical synthesized silver nanowires have been proved to be the efficient architecture for Plasmonic waveguides, but the high propagation loss prevents their widely applications.…
An all-dielectric bowtie waveguide with deep subwavelength mode confinement
Wencheng Yue, Peijun Yao, Lixin Xu
To fulfil both size and power requirements for future photonic integrated circuits, an effective approach is to miniaturize photonic components. Surface plasmon polariton (SPP) is…
Diffraction-Free Bloch Surface Waves
Ruxue Wang, Yong Wang, Douguo Zhang +11
In this letter, we demonstrate a novel diffraction-free Bloch surface wave (DF-BSW) sustained on all-dielectric multilayers that does not diffract after being passed through three…
Plasmonic lasing of nanocavity embedding in metallic nanoantenna array
Cheng Zhang, Yonghua Lu, Yuan Ni +6
Plasmonic nanolasers have ultrahigh lasing thresholds, especially those devices for which all three dimensions are truly subwavelength. Because of a momentum mismatch between the p…
Controllable directive radiation of a magnetic dipole above planar metal surface
Zheng Xi, Yonghua Lu, Peijun Yao +3
We report unidirectional radiation of a magnetic dipole above planar metal surface, the radiation direction can be manipulated via changing the distance between the dipole and the…
Plasmonic dark field microscopy with a polymer substrate
Yikai Chen, Douguo Zhang, Lu Han +4
In this letter, a plasmonic dark field microscopy taking advantages of the polymer loaded surface plasmon polariton waveguide (PLSPPW) is experimentally demonstrated. The dye molec…
Direct characterization of planar waveguide modes by Fourier plane fluorescence leakage radiation microscopy
Douguo Zhang, Qiang Fu, Xiangxian Wang +2
In this letter, the leakage radiation microscopy (LRM) is extended into characterization of planar waveguide modes (WMs) rather than surface plasmon polaritons (SPPs) taking advant…
Anisotropic surface plasmon-coupled emission from structured PMMA films doped with Rhodamine B
D. G. Zhang, X. -C. Yuan, G. H. Yuan +3
We report observation of anisotropic surface plasmon-coupled emission (SPCE) from structured PMMA films doped with Rhodamine B (RhB) and deposited on silver films. For a given stru…
Excitation of surface plasmon polaritons guided mode by Rhodamine B molecules doped in PMMA stripe
D. G. Zhang, X. -C. Yuan, A. Bouhelier +2
In this letter we show the inclusion of Rhodamine B molecules (RhB) inside a dielectric-loaded surface plasmon waveguide enables for a precise determination of its optical characte…
